名詞性從句是高考湖北卷完成句子題型的考查內(nèi)容之一，它有主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句這個(gè)四個(gè)類別。本文結(jié)合湖北省高考試題，談?wù)勗谕瓿删渥宇}型中中名詞性從句的運(yùn)用。

一、正確的語(yǔ)序和連接詞的確定

1._{Whether he has been abroad or not}(他是否出過(guò)國(guó)) doesnt make much difference. (abroad)

2. With the rapid development of science and technology, I cant imagine _{what my hometown will be like}(我的家鄉(xiāng)會(huì)是怎樣) in ten years.（what）

3. _{Whatever one has planned}(任何計(jì)劃好了的事) is sure to change as one puts it into practice. (whatever)

4._{What delighted the fans/What made the fans delighted}(令球迷欣喜的) was that the young player performed extremely well in the table tennis tournament. (delight)

5._{That we should stay clam}( 我們應(yīng)該保持鎮(zhèn)靜) in face of danger matters much in case of emergency. (stay)

從以上五個(gè)例句可以看出：名詞性從句的連接詞應(yīng)放在從句的前面，連接詞后面應(yīng)為陳述語(yǔ)序。從句的連接詞大部分可以從字面上確定，如1、2、3這三個(gè)例句。但也有字面上難以確定的情況，這個(gè)時(shí)候就連接詞在從句中所作的成分，如4、5兩個(gè)例句中的what和that。選擇what還是that的關(guān)鍵是看其在句中是否作相應(yīng)的成分，如果不作任何成分，就用that，如例句5；如果作了主語(yǔ)、賓語(yǔ)或表語(yǔ)，則用what，如例句4，what就在句中作主語(yǔ)。

If和whether在名詞性從句中不作任何成分，引導(dǎo)動(dòng)詞后面的賓語(yǔ)從句時(shí)一般可以通用，但介詞后的賓語(yǔ)從句、主語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句不能用if引導(dǎo)，只能用whether。例如：

1. However, scientists still wonder whether/if cloning will help or harm and where it is leading us. Whether在該句中引導(dǎo)賓語(yǔ)從句，可以用if代替。

2. It all depends on_{whether we can get their co-operation.}Whether在句中引導(dǎo)賓語(yǔ)從句，不能用if代替，因?yàn)樗诮樵~on的后面。

3. His first question was_{whether Holmes had arrived yet.}Whether在該句中引導(dǎo)表語(yǔ)從句，不能用if代替。

4. The question_{whether we ought to call in a specialist was answered by the family doctor.}Whether在該句中引導(dǎo)同位語(yǔ)從句，不能用if代替。

5. So whether life will continue on the earth for millions of years to come will depend on_{Whether this problem can be solved.}Whether在該句中引導(dǎo)主語(yǔ)從句，不能用if代替。

二、時(shí)態(tài)的一致性

1. I havent the slightest idea (of) _{what he is talking about}（他在說(shuō)什么）.

2. The fact_{that he has failed (for) several times}(他失敗了數(shù)次) makes him very upset. (he fail)

3. The news_{that the house prices will fall}(房?jī)r(jià)要下跌) has caused many people to sell their houses at lower prices.

從這三個(gè)例句可以看出，名詞性從句的時(shí)態(tài)受主句時(shí)態(tài)的制約，要和主句的時(shí)態(tài)保持一致。如：例句1的主句是一般現(xiàn)在時(shí)，從句是現(xiàn)在進(jìn)行時(shí)；例句2的主句是一般現(xiàn)在時(shí)，從句是現(xiàn)在完成時(shí)；例句3的主句是現(xiàn)在完成時(shí)，從句是一般將來(lái)時(shí)。

當(dāng)然，也有主句和從句時(shí)態(tài)不一致的情況，例如：

Do you know_{when the ancient Olympic Games began?}

When I was a little boy, the teacher told me_{that light travels much fast than sound.}

三、虛擬語(yǔ)氣的正確運(yùn)用

After circling around the earth for three days, Shenzhou Spaceship received the command from the ground_{that it (should) land}(它著陸) as scheduled the next day.

在上面的例句中，that 引導(dǎo)同位語(yǔ)從句作the command的同位語(yǔ)，所以用虛擬語(yǔ)氣。在名詞性從句中，虛擬語(yǔ)氣常常用于下列的一些句式中：

1. 在It is necessary/natural/important/strange ... + that從句中，從句中的謂語(yǔ)動(dòng)詞用“should+動(dòng)詞原形”表示虛擬語(yǔ)氣，且should可以省略。

It is necessary that I_{(should) get the text of my revision typed this morning.}

Ah, it is natural that you_{(should) forget it first.}

2. 表示“建議，命令，要求”的動(dòng)詞，后接that從句時(shí)，從句的謂語(yǔ)動(dòng)詞要用虛擬語(yǔ)氣，即“should+動(dòng)詞原形”，且should可以省略。

Bobs doctor_suggeststhat he_{(should) rest}for a few days.

He_orderedthat the work_{(should) be started}at once.

3. 表示“建議，命令，要求，想法”的名詞，后接that從句時(shí)，從句的謂語(yǔ)動(dòng)詞用虛擬語(yǔ)氣，即“should+動(dòng)詞原形”，且should可以省略。這類名詞有：advice, agreement, command, decision, demand, determination, order, preference, proposal, request, requirement, desire等。

He made the_suggestionthat they_{carry on}their conversation in French.

This is our only_requestthat this_{(should) be settled as}soon as possible.

同樣，如果主語(yǔ)是表示“建議，命令，要求，想法”等意思的名詞，后接that引導(dǎo)的表語(yǔ)從句時(shí)，從句的謂語(yǔ)動(dòng)詞要用虛擬語(yǔ)氣，即“should+動(dòng)詞原形”，且should可以省略。

His suggestion is that we_{(should) make}improvements in our service.

Their decision is that the school_{(should) remain}closed.
